TC1303B DUAL-OUTPUT REGULATOR USER’S GUIDE Chapter 1. Product Overview 1.1 INTRODUCTION The TC1303B Dual-Output Regulator with Power-Good Output Demo Board is used to demonstrate the operation of the TC1303B. The TC1303B combines a 500 mA synchronous buck regulator and 300 mA Low-Dropout Regulator (LDO) with a power-good monitor to provide a highly integrated solution for devices that require multiple supply voltages.
TC1303B Dual-Output Regulator User’s Guide 1.2 WHAT IS THE TC1303B DUAL-OUTPUT REGULATOR WITH POWER-GOOD OUTPUT DEMO BOARD? The TC1303B Dual-Output Regulator with Power-Good Output Demo Board can be used to evaluate the TC1303B device over the input voltage range and output current range for both the synchronous buck regulator output and the low-dropout linear regulator output. Test points are provided for input power, output loads, shutdown control and power-good monitoring. 1.
TC1303B DUAL-OUTPUT REGULATOR USER’S GUIDE Chapter 2. Installation and Operation 2.1 INTRODUCTION The TC1303B Dual-Output Regulator with Power-Good Output Demo Board demonstrates Microchip’s TC1303B Dual Output Voltage Regulator over its entire range of operation. 2.2 FEATURES The TC1303B Dual-Output Regulator with Power-Good Output Demo Board has the following features: • Test points for applying input voltage (0V to 5.
TC1303B Dual-Output Regulator User’s Guide Note: DS51563A-page 8 When grounding the shutdown pins, the input voltage is placed across the 1 MΩ pull-up resistor. This will cause the input current to increase by a few micro-amps. © 2005 Microchip Technology Inc.
